Single crystal growth and structural characterization of synthetic U(VI) peroxide phases, studtite (UO₂(O₂)(H₂O)₂·2H₂O) and metastudtite (UO₂(O₂)(H₂O)₂)

Key Points

• The research aims to synthesize and characterize synthetic uranyl peroxide phases including studtite and metastudtite.
• Utilized a H2O2 vapor diffusion method for crystal growth.
• Carried out direct structural refinement of the synthetic material.
• Performed controlled dehydration on synthesized crystals.
• Successfully synthesized studtite crystals using the vapor diffusion method.
• Achieved the first direct structural refinement of synthetic studtite.
• Investigated the structural behavior upon dehydration of uranyl peroxide.
